Rio, Alcoa, Apple in green aluminium bid

Rio Tinto aims to commercialise a new aluminium smelting process that does not generate carbon dioxide emissions within six years. The resources group will develop the Elysis process in partnership with Alcoa and technology giant Apple. Aluminium generates carbon dioxide emissions from both the smelting process itself and the electricity that is consumer in its production. Rio Tinto and Alcoa claim that the Elysis process is the industry’s most significant innovation in more than a century.
